Application Environments of Plastic Bellow Pipe

Plastic Bellow Pipe, made of materials such as PVC, PE, and PP, has a corrugated form. It is telescopic and can compensate for length changes caused by temperature, sedimentation, or thermal effects, reducing connection stress. The inner wall is smooth, which is convenient for fluid transportation. It is used in building rainwater and sewage discharge, municipal engineering drainage and irrigation, and as protective casings for wires and cables to prevent mechanical damage, chemical erosion, and moisture.

I. Building Field
(1) Rainwater Drainage System
In the roof rainwater drainage of buildings, Plastic Bellow Pipe plays an important role. Its telescopic property enables it to adapt to the thermal expansion and contraction of the building under different seasonal temperature changes, effectively preventing the pipe from cracking due to temperature stress.

For example, in summer when the temperature is high and the pipe expands due to heat, the corrugated structure can expand to accommodate the volume change; in winter when the temperature is low and the pipe contracts, the corrugated shape can avoid excessive compression and damage of the material. At the same time, the smooth inner wall ensures that rainwater can be drained quickly and smoothly, reducing the risk of water accumulation damaging the building roof and protecting the structural integrity of the building.
(2) Sewage Discharge System
For the sewage discharge inside buildings, Plastic Bellow Pipe is also applicable. It can withstand the chemical corrosion that may exist in the sewage, such as acid and alkali components. Moreover, its good flexibility can maintain the integrity of the pipe connection when the building settles or has slight displacements, preventing sewage leakage from polluting the building foundation and the surrounding environment and ensuring the long-term stable operation of the sewage discharge system.

II. Municipal Engineering
(1) Drainage Engineering
In the drainage systems of urban roads, squares, and other areas, Plastic Bellow Pipe is widely used. It can adapt to the complex underground environment, such as the slight deformation of the foundation caused by the ground traffic load. When the road vibrates or settles due to vehicle driving, the corrugated structure of the pipe can expand, contract, and bend, maintaining the smoothness of the drainage channel, effectively draining the road surface water, preventing urban waterlogging, and ensuring the normal order of urban traffic and residents' lives.

(2) Irrigation System
In the irrigation projects of municipal parks, green spaces, and other places, Plastic Bellow Pipe is an ideal choice. Its flexibility makes it easy to lay in different terrains and landscapes, and it can bypass obstacles to achieve a flexible layout. Moreover, the pipe can withstand a certain pressure, ensuring that the irrigation water is stably and evenly delivered to each irrigation area, meeting the water demand of plant growth, and reducing water waste and maintenance costs caused by pipe damage.
III. Wire and Cable Protection

(3) Mechanical Protection
During the laying of wires and cables, Plastic Bellow Pipe, as a protective casing, provides excellent mechanical protection for the cables. Whether in indoor or outdoor environments, it can prevent the cables from being damaged by external forces such as squeezing, collision, and friction. For example, when the cables pass through walls and floors in a building, or are laid along utility poles and cable trays outdoors, the protective casing can prevent the cables from being scratched and worn, ensuring the safe and reliable transmission of electricity and signals.

(II) Chemical Erosion and Moisture Protection
In some areas where there may be chemical pollution, such as factory workshops and chemical industrial parks, Plastic Bellow Pipe can resist the chemical erosion of the cables. At the same time, its good sealing property can prevent moisture from entering the interior of the casing, avoiding problems such as short circuits and decreased insulation performance of the cables due to moisture, prolonging the service life of the cables, reducing the risk of electrical accidents, and ensuring the stable operation of the power and communication systems.
